Ergonomics in the Operating Room
Operating room staff are known to have several risk factors for musculoskeletal disorders including the following:¹
These risk factors have led to a high rate of musculoskeletal disorders amongst surgeons and operating room staff, with reported discomfort due to operating room tasks ranging from 66 - 94% with pain typically occurring in the hands, arm, neck, low back and shoulders(Fig. 1).2
Uncomfortable postures Prolonged standing Holding retraction forextended time
Prolonged fixed posturesPulling/pushing equipment and/or patients during surgery.

Ergonomics Needed in the Operating Room
Broadly defined, the goal of ergonomics is to prevent soft tissue injury and musculoskeletal disorders caused by exposure to force, repetitivemotion, vibration and awkward posture.3 Practically, ergonomics is the concept of designing a working environment to fit the worker, rather than forcing the worker to fit the environment.2 While principles of ergonomics have been applied in various industries since the early 1900s4, in the medical field, ergonomics applications didn’t gain interest until the early 1980s, with adoption of ergonomic principles continuing to be slow, even today. In the operating theatre in particular, one of the main ergonomic considerations is visual exposure of the surgical field. Exposure can be aided by proper positioning of the patient and the application of retractors to the wound and internal tissues.5
The shoulder/upper arm should remainperpendicular to the floor
The angle between the forearm and upperarm should be 90º
Neck flexion should be about 20º and excessivehead forward posture should be avoided as thiscan increase damage to the cervical spine
Short breaks should be undertakenapproximately every 20 minutes during asurgical procedure
The forearm should be held in a horizontalposition, parallel to the floor and in a neutralposition between supination and pronation
Extreme wrist excursions should notoccupy >30% of operating time
Ergonomics Guidelines
In order to help with surgical ergonomics, the AORN in 2011 recommended the use of self-retaining retractors whenever possible.6
Further, several recommendations have been put forth in ergonomic guidelines for surgeons and OR staff including:²

Lack of Ergonomics Implementation
Despite surgeon and OR staff understanding of the importance of ergonomics within the operating room, there are several reasons for alack of implementation of such solutions. Unlike other industries, standardization is difficult due to human anatomy, each patient’s surgeryis unique, and different surgeons often use different surgical approaches and set-up for similar procedures.7

The Walter Difference
The WalterLorenzTM Surgical Assist Arm is a bionic, electromechanical arm that enables surgical site optimization. The Walter Arm wascreated in collaboration with surgeons across multiple disciplines to assist with visual access, flexibility, and efficiency during surgicalprocedures. The Walter Arm is designed to retract tissues with steady pressure, alleviating the retraction burden and associated ergonomic/injury risks to the surgeon and operating room staff. By providing a stable platform, the Walter Arm may help to reduce fatigue and stress in operating room personnel, thereby reducing injury to surgical staff and improving overall surgical ergonomics to enhance operative efficiency and safety.
